macro setup not working
Although my question has probably been answered many times previously I need some answers now. I have exhausted time delving into the forums looking for answers but after a reas time have called a truce. Am ready I think to start taking pics, am using a D750, 100mm bellows. a Nikkor 200mmF4 lens and a Nikon Plan 10x micro. When I shine light on a subject all I see thru the camera is a pretty prism type coloured effect. I can visualise some shadow as I move my hand in front of the lens but no detail at all of the subject for testing---none at all as if it doesn't exist. Do I need to set the F4 up specifically ? If so how, is that my problem ? Can somebody pls share some thoughts on what I am doing wrong----pleeeeez !

Set up pics shown below. not sure where the pics have gone ? Bellows is at 100mm, then F4 Nikkor manual lens wound around to infinity marking. Lighting at present is 2 x 60 watt LED lights. Tried others but no different. Just can't see anything to even suggest my lighting is a problem.

Thanks rolsen for the comment. Tried as you suggested but no change, ie I cannot see anything thru the lens no matter if distance is close / far and with all lens ranges used. Its as if there is a "block" of vision. Is there a way to check that the Micro objective is sound ? Not been dropped but who know's. Ideas ?

Please see if you have this checked under the message field:hotrodder19 wrote:Perhaps somebody could explain how I upload pics to my post ?

"Disable BBCode in this post". If so, uncheck it and submit the message again. You can also use the preview-button to make sure all is visible.

hotrodder19, I'm guessing that when uploading the images you accidentally omitted step 5 at Image Hosting Steps... :
As admin, I found the following images recently uploaded by hotrodder19:
I will let other people diagnose the problem with the optics.
At this moment I am very confused because I don't see a "Nikon Plan 10x micro" anywhere in the images. Where is it?

5) The upload window will now preview the image you have chosen to upload. You will probably have to enlarge this window or use the scroll bars to see the entire image and the important controls, which are at the bottom of the window. To insert the necessary BBCode into your posting, click on the blue part of "insert picture: standard" or "insert picture and upload another one" (red arrows). (Do not click on the black words "insert picture". Nothing will happen if you do that.)

I agree completely, ... although I suppose the Nikon 10X is in the front, although we can not see it.Deanimator wrote:
- I don't see an objective anywhere either.
- Is it just me, or does anyone else see a visible droop after the bellows?
As Deanimator has told you, the bellows is not necessary (I suppose the Nikon 10X is infinite).
So:
1) remove the bellows. (the drop will also be eliminated)
2) Focus the Nikkor 200mm to infinity (for example, focus on the moon)
3) do the test
Please, when you mount the setup, show it to us so that we can see the Nikon 10X ....

And a confirmation of and a closeup of the objective would be a big help.RDolz wrote:I agree completely, ... although I suppose the Nikon 10X is in the front, although we can not see it.Deanimator wrote:

If it's absent... or a finite objective, those are instant show stoppers.
I'll be the first one to admit that using objectives was at first confusing for me. It's entirely possible that a misunderstanding has led him to mount a finite objective on BOTH a tube lens and bellows.
Barring a problem with the tube lens (or a used objective), this should be a pretty easy problem to remedy.

The camera works ok with the Nikkor 200mm lens. I can see fair detail with the micro objective looking thru it when removed.
THoughts now please hotrodder19

I feel like I'm still seeing a couple of short extension tubes mounted behind the 200 mm. If there are, then take those away.
Set the aperture on the 200 mm to be wide open. Right now it looks like it's f/32.
After that -- when your optics are just camera, 200 mm lens wide open set on infinity focus, and the objective -- then the system will focus on an object that is located 6.7 mm in front of it. That's what the "WD 6.7" printed on your lens means: "working distance 6.7 mm".
